3 Questions
What are root hairs and how do they function?
Root hairs are unicellular elongations of epidermal cells that help absorb water and minerals from the soil.
What are trichomes and what is their role in the shoot system?
Trichomes are epidermal hairs on the stem that are usually multicellular. They may be branched or unbranched, soft or stiff, and even secretory. Their role in the shoot system is to help prevent water loss due to transpiration.
How do root hairs and trichomes differ in structure and function?
Root hairs are unicellular elongations of epidermal cells that absorb water and minerals from the soil, while trichomes are usually multicellular epidermal hairs on the stem that help prevent water loss due to transpiration.
